Excesso de adiposidade corporal em adolescentes: associação com fatores sociodemográficos e aptidão física High body fat among adolescents: association with sociodemographics and physical fitness factors
Abstract
Objetivou-se verificar a prevalência e os fatores sociodemográficos e de aptidão física associados à adiposidade corporal elevada (ACE) em adolescentes de Januária-MG, Brasil. A amostra foi de 266 rapazes e 361 moças (15,47±1,06 anos). A adiposidade foi estimada pelo somatório das dobras cutâneas tricipital e subescapular. As variáveis independentes foram: zona de domicílio (rural e urbana); idade (14-15 e 16-17); nível econômico (alto, médio e baixo); aptidão aeróbia, flexibilidade e resistência muscular (adequada e inadequada). Nos rapazes, 13,91% apresentaram ACE, com maior somatório de dobras cutâneas sendo observado nos residentes da zona urbana (pThe objective was to verify the prevalence and factors associated with high body fat in adolescents from Januaria-MG, Brazil. The sample included 266 boys and 361 girls (15,47±1,06 years old). Adiposity was estimated by the sum of triceps and subscapular skinfold thickness. The independent variables were: area of residence (urban and rural); age (14-15 and 16-17 years old); house income (high, medium and low); aerobic fitness, flexibility and muscular resistance (adequate and inadequate). Among boys, 13,91% exhibited adiposity excess, with higher (p<0.05) skinfold thicknesses sum been observed among boys with low house income and urban residence. Among girls, 33,24% exhibited adiposity excess, with higher (p<0.05) skinfold thicknesses sum been observed among girls with 16-17 years old and low house income. Adiposity excess was associates, only in boys, with urban residence and inadequate muscular resistance. Thus, boys seem to be more susceptible to environmental factors than girls.
